Maggy can see!!!

Ok, so a little over the top maybe 😉 but I’ve finally got a workable visibility solution which (whilst still not perfect) means Maggy now only submits what should be visible to the GPU to be rendered. By and large, anyway!

The reduced geometry burden means the increase in performance allows me to increase the level of detail (vertices and triangles) for terrain near the camera, so I now have to retune the LOD algorithms (which were fairly stump-stupid-basic).
